2011 RTE, France

Beginning of 2009 RTE, France, a state-owned limited company, a subsidiary of the EDF Group, ordered 5 MSCDNs from Siemens.

The MSCDN (Mechanically Switched Capacitor Damping Network) incorporates only passive components such as capacitors, reactors and resistors and can be connected directly to the high voltage busbar system

The MSC is used to stabilize system voltage and to keep voltage fluctuations caused by heavy load variations and changed network conditions within acceptable limits.

The completion date is planed in 2011.

Type:

MSCDN

System Voltage / Frequency:

2006 Benejama and Saladas, Spain

Site view of La Saladas substation

In July 2005 Siemens received the follow-up order from Red Eléctrica de España about two new MSCDN systems (220kV, 100 MVAr) in the substations Benejama and Saladas near the Costa Blanca in Spain. This is the result of our customers satisfaction received by the Siemens project management during the first order, the Jijona MSCDN.

The installation of MSCDN like for Benejama and Saladas are used for voltage control and network stabilization under heavy load conditions with an additional damping circuit for avoidance of system resonances.

The completion date was in the first quarter of 2006.

2004 Kuala Lumpur MSC, Malaysia

The Kuala Lumpur MSC turnkey project was awarded to Siemens by TNB (Tenaga National Berhard), Malaysia in 2003. The MSC are installed at KL North substation. KL North is one of the most important substations for reliable supply of energy for Kuala Lumpur. The MSC are used for voltage control and network stabilization under heavy load conditions.

Turnkey Project

2003 SEC – Baish, Saudi Arabia

Siemens as a trusted supplier for FACTS devices got the order for the Baish MSC from SEC (Saudi Electric Company) in 2003. One year later SEC ordered 4 additional MSCs, the Samitah project from Siemens.

Two shunt capacitors (MSC) have been installed at Baish 132 kV substation in Jizan region of SEC-SRB. MSC are a simple and effective compensation method for the system. The shunt capacitors are used for Reactive Power Control and AC network stability.
